Why Trezor Bridge?

Trezor devices communicate with desktop browsers through a dedicated local bridge rather than directly exposing the device to the web. This improves compatibility across browsers and operating systems and ensures messages are routed locally—your private keys never leave the device.

Quick setup (Windows / macOS / Linux)

1. Download: Visit the official Trezor download page and get the latest Trezor Bridge installer for your OS.
2. Install: Run the downloaded installer and follow on-screen prompts. Administrative privileges may be required.
3. Connect: Plug in your Trezor device via USB. Your operating system should recognise the device.
4. Open a web app: Launch Trezor Suite or a supported website that uses Trezor. The web app will detect Bridge and prompt to connect.
5. Authorize: Confirm connection prompts on your Trezor device when requested. Always verify any address or transaction details on the device display.

Troubleshooting tips

Tip: If your browser fails to detect the device, restart the browser, reconnect the USB cable, or reinstall Bridge. Try a different USB port or cable if problems persist.

• Ensure you installed the official Bridge installer from the Trezor website.
• Temporarily disable VPNs or strict firewall rules that might block local network communication.
• Use a current, supported browser; some browsers require additional permissions for local connections.

Security reminders

Trezor Bridge only provides a local communication channel. Your seed and private keys remain stored on the device. Never install Bridge from third-party sources and never enter your recovery seed into any app or website. Always confirm on-device prompts before approving actions.
